Not sure why this is being downvoted, since it appears to be accurate (searching for "remote sensing agriculture" only yields results about aerial/satellite imagery), and the linked paper contrasts "remote" (aka aerial) with "ground-based".
That usage is quite problematic though, because, by using such a broad term for such a specific application, you lose the ability to use it to describe other valid "remote sensing " instances such as those implemented by the OP.
